adjusting the threaded rod(s). There should be no gap
between the bottom of the external supply plenum
and the hood after installation and adjustments are
completed.
2. The external supply plenum should be resting
lightly against the hood. The hood is only used to
position the plenum; it is not intended to support the
plenum. All hanger brackets on the external supply
plenum must be used and the plenum must be
properly supported while lifting to prevent damage or

3. It is recommended that caulk be applied at the
mating seams and surfaces of the external supply
plenum, the hood, and the wall. If the external supply
plenum is next to a wall, you will need to caulk
around the surface next to the wall. Caulk the joints
with NSF Approved silicone caulk (GE SCS1009, or
its equivalent). The caulk is not provided.

Installing the Supply Duct Collar to the Plenum

Place the duct collar(s) over the opening, fastening
with tack-welds at 1 to 2 in. (2.54 to 5.08 cm) intervals,
or sheet metal screws at 3 to 6 in. (7.62 to 15.24 cm)
intervals. It is suggested that the duct collar be attached
